The analyst's take on Littelfuse, Inc.
Littelfuse, Inc. has grown revenue from $1.06B to $2.39B over the last 10 fiscal years, compounding about 10.5% a year. The most recent year was up 8.9%, so growth has cooled from its longer-run pace.

At today's valuation the market is pricing in roughly 13.4% annual free-cash-flow growth — versus the 12.6% it actually delivered over the last five years, broadly in line with what it has delivered. The one thing worth a second look in the filings is currently unprofitable.
